2.8 Function annotation of putative CAZymes.
CAZy is a carbohydrate-active enzymes(CAZymes)database(http：//www.cazy.org/)［25］，which classify the CAZymes into 5 major modules：Glycoside Hydrolases(GH)，Glycosyl Transferases(GT)，Polysaccharide Lyases(PL)，Carbohydrate Esterases(CE)，and Carbohydrate-Binding Modules(CBM).We mapped our analyzed fungi genomes to CAZy to study the members and features of those Carbohydrateactive enzymes.The results revealed that the gene numbers in the 5 major modules of CAZymes were similar in Agaricomycotina fungi，while much fewer in Ustilaginomycotina and Ascomycota fungi.As others，G.lucidum possessed a wide spectrum of CAZymes responsible for the biosynthesis，degradation and modification of oligoand polysaccharides，and of glycoconjugates(Table 6).The GHs and CEs in G.lucidum showed a little more than the average count，while GTs，CBMs and PLs showed less than the agaricomycotina average(Table 6).
